“…They exhibit a distinctive seasonal geoid height variation pattern with maximum values at the beginning of spring and minimum values at the end of the summer. This seasonal pattern is consistent with the hydrological cycle in the investigated area (e.g., Krynski et al 2014). The results presented in Figs.…”

“…The first one which will overlap with GRACE mission is GRACE Follow-on (GRACE-FO) mission that has been scheduled for launch in August 2017 (e.g., Flechtner et al 2016). During the past years, many investigations (e.g., Tapley et al 2004;Chambers 2006;Swenson and Wahr 2007;Luthcke et al 2013;Krynski et al 2014;Wu and Heflin 2015;Guo et al 2016) concerning the determination of temporal mass variations in the Earth system using GRACE data have been conducted worldwide. For temporal geoid height variations, Rangelova (2007) combined GRACE data with GNSS, tide gauge/altimetry, and absolute gravimetry data to develop a dynamic geoid model for Canada.…”

“…Rangelova et al 2010). Krynski et al (2014) conducted a research for analyzing variations of the Earth's gravity field over the whole area of Europe using release 04 (RL04) GRACE-based global geopotential models (GGMs). They showed that amplitudes of geoid height variations for the area of Central Europe reach up to 7 mm.…”

“…In this contribution, the focus is put on the latest release, i.e., release 05 (RL05), GRACE-based GGMs and temporal variations of geoid heights over a smaller area [higher spatial resolution than in Krynski et al (2014)]. The area of Poland, bounded by parallels of 49°N and 55°N and meridians of 14°E and 24°E, has been chosen as a study area (Fig.…”

Temporal mass variations in the Earth system, which can be detected from the Gravity Recovery and Climate Experiment (GRACE) mission data, cause temporal variations of geoid heights. The main objective of this contribution is to analyze temporal variations of geoid heights over the area of Poland using global geopotential models (GGMs) developed on the basis of GRACE mission data. Time series of geoid height variations were calculated for the chosen subareas of the aforementioned area using those GGMs. Thereafter, these variations were analyzed using two different methods. On the basis of the analysis results, models of temporal geoid height variations were developed and discussed. The possibility of prediction of geoid height variations using GRACE mission data over the area of Poland was also investigated. The main findings reveal that the geoid height over the area of Poland vary within 1.1 cm which should be considered when defining the geoid model of 1 cm accuracy for this area.

“…With such a fit, temporal variations of geoid heights seem important to be investigated and taken into the consideration. Krynski et al (2014) conducted research for analysing temporal variations of the Earth's gravity field over the whole area of Europe, including the area of Poland and surrounding areas. The authors analysed release RL04 GRACE-based Global Geopotential Models (GGMs) using Fourier's analysis (e.g.…”

Temporal variations of geoid heights are vitally important in geodesy and Earth science. They are essentially needed for dynamic and kinematic updates of the static geoid model. These temporal variations, which substantially differ for different geographic locations, can successfully be determined using the Gravity Recovery And Climate Experiment (GRACE) mission data. So far, statistical decomposition methods, e.g. the Principal Component Analysis/Empirical Orthogonal Function (PCA/EOF) method, have not been implemented for the analysis and modelling of temporal mass variations within the Earth's system over the area of Poland. The aim of this contribution is to analyse and model temporal variations of geoid heights obtained from GRACE mission data over the area of Poland using the PCA/EOF method. Temporal variations of geoid heights were obtained from the latest release, i.e. release five, of monthly GRACE-based Global Geopotential Models. They can reach the level of 10 mm. The PCA modes and their corresponding EOF loading patterns were estimated using two different algorithms. The results obtained revealed that significant part of the signal of temporal variations of geoid heights over Poland can be obtained from the first three PCA modes and EOF loading patterns. They demonstrate the suitability of the PCA/EOF method for analysing and modelling temporal variations of geoid heights over the area investigated.
